From data input to optimized envelope in 4 steps
Try the live app right now — no sign-up required. Or watch the 90-second walkthrough below.
Input Building Data
Province (auto-fills design temperature), room type, floor count, area, building rotation, façade dimensions per direction, and internal loads from people, equipment, and lighting. The more detail, the more accurate the result.
Read the Heat Load Chart
Total BTU, OTTV (W/m²), Tons of Refrigeration, plus a bar chart breaking down heat from walls, glass, roof, people, and equipment — updated in real-time. Spot the "villain" before optimizing.
Slide to Optimize
Adjust wall R-Value, glass SC, roof insulation, and infiltration. See BTU drop, annual savings appear, and % savings vs. baseline updated in real-time. Find the sweet spot between cost and performance.
Layer-Level R-Value
Need higher precision? Open the Layered R-Value Calculator (sister tool) to design walls layer-by-layer (concrete + EPS + gypsum), then return the aggregate R-value into the main app for exact results.
